Unironically you're missing the point. The point being, it's not a problem for many apps to start because oh how powerful PCs got. The problem is when some apps use so much resources that regardless of how powerful your PC gets, it's wasteful to have them opened all the time.
Reason for that problem is them using unoptimized frameworks such as Electron and CEF (seriously, check each app on the image).
And main reasons for that are:
Google posing browser component as a GUI framework.
Devs not caring (or being lazy) enough to do native coding.
I wish every person would realize the above so we could force developers do their job better.
Ironically, even if OP missed the point, the apps pictured are resource hogs and all of them don't need to run on starup other than Defender.
Sure, leave OneDrive/Dropbox on if you use it. Leave Spotify if you just need your music to start blasting the second you reach the desktop. If opening Steam and waiting ~30 seconds for the lord Gaben-given daily update is too much of a problem let it do its thing on startup, but who in their right mind needs Soptify, OneNote and all the gaming clients slowing down startup of literally everything?
And CCleaner, McAffee and Adobe can go fuck themselves along wirh Nestle.
Even Windows doesn't really even need a 3rd party anti-virus anymore. The built in windows defender has gotten so good as to really be all you need for active protection unless you're insanely stupid and keep bypassing it. Use Malwarebytes for deep file scans once in a blue moon, and you're golden.
Hate to tell you this, but Linux nor MacOS are safe without AV
It's just Windows, by far, has the largest share of active systems so everyone targets it. Both MacOS and Linux have their own share of bonafide viruses though
